Tom, that's what I'm doing, running the headphone out to a Pyle amp. I pulled the downstairs TV out and indeed Liberty has speaker wire coming out of the TV vents. I'll bury the amps behind the TVs and use the TV audio controls.
Gary, your Bose must have IR control. Ours has RF only and I haven't found a way to translate IR to Bose RF.
Oh, missed that. Yes, could. There are overhead speakers separate from the Bose that I want to continue using, so the headphone out will go to the Pyle amp which will drive the two overhead Alpine speakers. It will be set up that way in the salon, bedroom and down below. In the salon, the audio out from the satellite receiver (which will also handle the antenna & cable TV) and the DVD player will go to the Bose Video 1 and Video 2. My computer iTunes goes wirelessly to the Bose Aux. The way Liberty has this set up, I can turn on the TV and have audio separate from the Bose. I can also play the TV audio and the Bose audio at the same time for really big sound.Originally Posted by truk4u

Jim,
Liberty must have just cut the internal speaker wires and then hooked the externals. I haven't opened up the old TV, but I doubt they had any kind of built in amp, what do you think?
The TVs do have a built in amp. In our JVCs it's 1W x 2. I doubt Liberty buried any additional amp inside the case. The new TVs will be here next week and when I get to it, I'll crack open the JVC cases and take a look. If I'm going to donate the old TVs, I guess I should rehook the speakers. Would anyone take them? They may be just junk.
This project is mostly done. Still doing a few refinements, but it is nice and up-to-date having high definition wide screen TVs in all the original places. Tom, I did use those Pyle amps on each TV and they do a great job of getting sound out of the 5-1/4" speakers.
When inverting power, there is a "buzz" in the background that I presume is from the modified sine wave inverters. I haven't found a filter.
The living room and bedroom audio items are on the same circuit. Perhaps I could do a small pure sine wave inverter just for that circuit? Haven't thought how that would wire up.
Or I guess I could replace the inverter on that leg with a new pure sine wave inverter. That sounds like a big event.
Any other thoughts? I guess I could just have good audio when plugged in or the generator is on and give up on the dry camping for good audio. Really rather have it good all the time.

Jim I get the Buzzin" from my radio speakers if the radio is revieving DC power whether or not it is turned on. Is there a filter for this problem? I'm assuming the buzz is generated by the inverters charges.

Is this a radio connected to your chassis batteries, like a car radio would be? Or is it a radio portion of a receiver/tuner? Odd that the buzz would be there if the unit is off, but it seems I heard that over my Bose system. When the main amplifier is off, the subwoofer still has power. I removed a factory installed filter and the buzz went away. This had something to do with things being on different circuits and is called (something like) ground interference, but I don't know for sure.

Hi Jim,
Our TV's are hard wired into the ceiling speakers by Liberty. Essentially, they simply cut the internal speaker wires and routed new wires through the back of the set, which terminate in plug ends.
These plugs then match up to plugs behind the set that run to the overhead speakers. When I replaced the bedroom TV, I followed the same procedure, which worked great!

Jim I don't know where it gets it power, but it is the dash radio that then goes to a equalizer, and amp then on to about 8 speakers. It is not the TV/VCR system. Where was your filter located in the system?
GregM
I'll guess this is the radio that your use while driving . . .
It sounds like yours is something with the engine side and I've heard about line filters you can install on the back of the radio, maybe in-line with the incoming power. I think I had one installed on an earlier motorhome. I'd check with Radio Shack or Best Buy.
